The   Math Working Group  has published the First Public Working Draft of   MathML Core . The MathML Core specification tries to address several issues related to implementing MathML in browsers. The  MathML3  specification has been difficult to implement for browsers, because it is big and does not contain very precise rules for rendering math formulas. MathML also has several parts that are not useful in browsers. The MathML Core specification tries to define an appropriate subset of MathML, describe its rendering in detail (using rules from the TeXBook and the Open Font Format as basis) and clarify the interactions of MathML with other parts of HTML and the Open Web Platform. The Math Working Group is also working on the rest of MathML. It is defining MathML4, the fourth version of MathML. The features included in MathML Core may evolve, or a second version of MathML Core may be defined, depending on how MathML4 develops.

  W3C is pleased to announce the  report from the W3C Workshop on Smart Cities , held on 25 June 2021. The main goal of the workshop was to improve and finalize the description of the  draft Charter for a potential Smart Cities Interest Group  so that we can launch the Interest Group and start further discussions on (1) interoperability for Web-based Smart City services and (2) use cases and requirements that W3C specifications need to meet to support Smart City services. Workshop discussions: Identified Smart Cities standardization stakeholders to drive the development of Web standards aligned with the real needs of Smart Cities Clarified reasonable applications for Smart Cities technologies Pointed out how to improve the draft Charter for the potential Smart Cities Interest Group As a concrete next step following the workshop, W3C will finalize the draft Charter hoping to launch a Smart Cities Interest Group and start further discussion within the group.
